Write an equivalent expression for 9 y + 2 y + 5 -2

An equivalent expression would be:

11y + 3

You would combine like terms, so 9y + 2y = 11 y and +5 - 2 = +3.

The simplest equivalent expression you would be able to have then is 11y + 3

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
